This paper investigates how common interaction techniques for large displays impact on recall in learning tasks. Our work is motivated by results of prior research in different areas that attribute a positive effect of interactivity to cognition. We present findings from a controlled lab experiment with 32 participants comparing mobile phone-based interaction, touch interaction, and full-body interaction to a non-interactive baseline. In contrast to prior findings, our results reveal that more movement can negatively influence recall. In particular we show that designers are facing an immanent trade-off between designing engaging interaction through extensive movement and creating memorable content.
